Be known that .Fniinnnion W'. Hoon s'iii'r'inii, a citizen ofthe UnitedStates', and

a resident of New- York, county and `State 'of New York, have inventedycertain new and useful improvements in Framing Devices forMoving-Picture Machines, of

'f which the following is a full, clear, and eX- act specification.

l This invention relates to a class of ap-y pliances adapted to-beused'in conjunction' with moving pictnre'machines.

My invention has for its object primarily l to provide a framing devicedesigned to be applied to a camera when animated pio' tures of objectsare taken as well as being' slide having an aperture of a'size wherebypartsv of predetermined dimensions of a .moving picturel strip'. r'whentransmitted through the machin I nay be successivelyv Sbjxposed vto thelens Y.well as being movably inaintainedin h pt ical axis thereof. Otherobjects of vthe "tipii 'are to.. provide manually operative.' meansforadjust-- ing .the ,apertur'ed slideg'v v`and -to'provide meanswhereby the guide and the slide .may

be yiel'dingly moved intermittently to allow freetransmissionfofthestrip vthrough the framing device;v A

" A further-object of the invention is to 4.0 provide a framing d eviceof a simple and efficient construction which is susceptible of beingmade: for use in conjunctiongwitli moving. picture machines oi varioustypes.

A- practical embodiment of the invention is represented in theaccompanying drawing forming a part of this specilication in whichsimilar characters of reference indicate corresponding parts in allthej.views, the said invention being more fully de- Ascribed hereinafter, andthen pointed out in theclaims at the end of the description.

liigg. is 'a detail sectional view, partly fragmentary, taken on theline V-V ot Fig. l.

.The framing device has/a guide, or supporting plate 10 whichv may be ofany suit- 70 able size and shape,though the plate is preferablysubstantially rectangulanand when the device is employed this plate isdisposed inja vertical position, as shown, on the front o the frontplate, as 1l, of the oper- 75 ating. mechanism of a camera for takingmoving pictures on a film, or strip,` :as 12,

as well as being applied on the front of the front plate of theoperating'mechanism of a projecting apparatus for exhibiting ,thepictures. The front plate 11 of the moving picture machine may be-of aform provided with-a vertically disposed groove, as at 13, andhaving anexposure window 14 there through centrally of the groovebesides-beingprovidedwith Aa swinging plate, as 15, -f or closing andopeningltlie passage through the window vwhen desiied The lower end ofthe supportingplatefjl. is held on a short shaft 16 which -is Qurnaledin spaced brack- 90 ets 17 and 18 arranged on the front plate 11 of themachine, and encircling this shaft a spiral springil9 having one endengag ingjtlie front plate of the machine while the second end of thespring engages the supporting plate. The supporting plate 10-astliushinged to the front plateof the machine will be permitted to beswungfrom and toward the front plate, the spring 19 normally' serving toyieldingly hold the 10o supporting plate against `the front pla-ie. lnthe rear -surface of the supporting plate. l() is a vertically disposedgroove 20 which is .of a width corresponding to the width.

oi' the groove 13 or the front plate oi the M5 4 machine, and thesegrooves are in communication. Through the supporting plate is a window2l in register with tiie'window 1d oic the front plate of the machine,and in 'the lower part of the supporting plate may ilo l In thecommunicating grooves 13 and 2()y the supporting plate 1() and of theiront "plate of the machine, is a slide 26 having an aperture 27therethrough,and this aperture is of a size corresponding to thedimension of the pictures on the iilm or strip. apertured slide 26 ispreferably in the `form of a plate of a size whereby it may be freelyadjusted upwardly and downwardly in the grooves 13, and 2O crosswise ofthe registered passages of the windows 14 and 21 for being arranged inthe optical axis of ,a lens, as .28, held in a barrel, as 29, which maybe provided in any suitable manner in front of the windows 14' and 21.Projecting from the upper part of the slide 26 is a bolt, or pin 30movably disposed through the slot 24 of the supportingplate 10, whilefrom thel lower part of the slide is a bolt, or pin 31 which movablyextends through the slot 25 of the supporting plate, and these boltsserve to permit the slide to be accurately guided in the grooves 13 and20.

In order to allow the slide 26 to be manually ,adjusted .for varying theregistration ot its aperture 27 with the windows 14 and 21,v

a lever, or handle, as 32, is provided. The lever, or handle 32 ispreferably in the 'form of a bar which -is ulcrumed, at 34,` to the'upper part of the supporting plate 1() for being disposed transverselyof the slide, and this bar is of a length so that one of its ends isarranged above the slide while its other end extends some distancelaterally with respect to the supporting plate. To the end of the bar,or handle 32 above the slidev 26 is pivoted,'at 35, one end of a link`36 having its other end pivotally held to the bolt 3() of theslide'eXteriorly of the supporting plate 10. y

When'the moving picture lilm or strip is transmitted through a camera,or projectingA apparatus having this framing device applied thereon, thesupporting plate 1() with the slide 26 is swung outwardly from' The n ul n, opening 23 or the :ont plate oi' the ma line t'or r ,ving picture si whereby i'ttentlv transini ed so that successive .l 1 l r i seu to thephotoerture 2"? of the slide 26 and through the window 21 of thesupporting fate 10. By accordingly i ini-'ing the lever 32 the slide 26will be adjusted inupward and downward directions so that the aperture27 will cause the exposure of the strip 'to be maintained in the opticalanis of .the lens.

'llo hold the-moving picture strip in movable engagement with thesprocket 37,'on the lower part of the front of the supporting plate 10are secured the lower ends of two spaced spring'ngers 39 and 40 both ofwhich extend upwardly toward the center of the opening 22 of thesupporting plate, and on the upper ends `oi` these spring lingers is abar 41 projecting across the'center of the opening. To the bar 41 isconnected a block, as 42, disposed back of the supporting plate 10 so astofyieldingly contact with the moving picture strip for releasablyholding it on the teeth of the sprocket.

Serving as means to intermittently swing the guide,.or supporting plate10 in. spaced relation to the front plate 11 of the machine for allowingthe moving picture strip to be ,freely transmitted through the framingdevice, projecting laterally fromthe support plate is a bar 43 having athreadedopening in its free end in which is screwed a threaded bolt, as44, and one end of this bolt is adjustably disposed in an opening 45provided in the front plate 11 of the vmachine for being engaged atintervals by the ends of a substantially rectangular cam, or block, vas46, held on a shaft 47 which is rotated bythe operating mechanism ofthe-maeliinanot shown, so as` to contact with the bolt 44 simultaneouslywith the engagement of the teeth of the sprocket 37 with the strip. Thecontacting of the cam 46 with the bolt 44 will cause the supportingplate 10 with the slide 2O to be spaced from the front plate of themachine at intervals, and the strip will then be freely moved by thesprocket.

ing lens through l ies` `lhen the bolt 44 is properlyadjusted fOI .wellas-being adapted for use on a project- -ing apparatus when the picturesare lexhibited on a screen whereby a moving picture strip, or film maybe transmitted so that successive parts of predetermined dimensions inaybe successively exposed to the .lens as well as being movably maintainedin its optical axis.
